Doing Coils Again: Ford 7K Springs Sagged

Well, my 7k Ford coil springs are going in the trash. About 2 years old and the left front of the truck is about 5/8" lower than the right. One would think a pair of new of new OEM 7k coils (designed for a F550) would hold-up in an F250. Apparently not.

Going with a set of these: http://www.sdtrucksprings.com/index....ducts_id=10188. These springs are 3,750 lbs each (7.5k combined) and aren't manufactured in Mexico.

Also plan to remove my Icon 1" TEI spacer at the same time. Hope the new setup will last.

Skan, just do it right, you will be happy if you got these: your ride will be 10x better and you can adjust the height anytime in under 5 minutes, so if its not level, you can adjust it level, if the springs sag, you can adjust it right back where you want. These are similiar to what I run, mine are just the 12"/ dual-spring version. I adjust them all the time!

If your interested PM me before you buy we can talk spring rates. If you stuff springs for the lift those will be fine, but if you need heavier springs for a plow or whatever I can give you the rate (# on the king coil) you would need, truck Toyz can get a heavier duty spring for you with that package - same price

The '05+ trucks all sit low on the drivers side. Most of them at 1/2"-1" low straight off the dealership lot. Due the all of the extra weight on the drivers side the only way for them to sit level is to run either a taller spring, or stiffer spring on the drivers side. You could also run a small coils spacer from PMF.

Hey jetjock is there a big difference in the icon vs king coil overs? As I'm thinking of going to a coil over set up in an 8" lift range

I prefer kings because I can get parts be it springs or valving anyway and any shop in Vegas whereas icons would be a bit harder to source. Icons should be a little cheaper and there springs and valving are probably more difficult to change youself, as there not as off-the-shelf if that makes sense. Nobody can argue kings place in shocks (#1), but I'm a huge Fan of Icon stuff, huge fan, you probably get a more specific valved/sprung coilover out of the box from them- That make sense? I'd feel comfortable ordering "icon coilovers for superduty" from anybody, and they probably be spot on. I would only order kings on the other hand from Carli or TruckToyz (for 8" call TruckToyz) cause the shop has to order the spring rate and valving from king and they know the tried and true combo. Bottom Line is King is the best out there for all off road application period - but specific to superdutys, Icon is top notch and has done there R&D, if there cheaper, I'd take a set in a heartbeat.

Guys - Thanks for the input. I periodically carry a large Lance camper, and unlike travel trailers and 5vrs, all the weight is on the truck. So in addition to weight carrying capacity, I actually like a stiff front spring to help with stability, sway, and front to back oscillation. That's why I went to the Ford 7k lb coils. Was a huge improvement over my OEM 5,200 lb coils which would allow the truck to bottom-out turning into my suburban driveway.

I like the idea of the 1/4 coil shims if needed in the future, to compensate for the trucks being heavier on the left, which I refer to as the "Super Duty lean".

I do appreciate the experiences and expertise that folks bring to this forum. Really helps us all learn.
